Not good! Sometimes if you overheat pla and don't print for too long it causes a jam in the print head.

Maybe you should turn on your heatbed. Walk away and then after 10 minutes start your print.

Personally I always set the temperatures in Cura all to 0. This makes it so that Cura doesn't wait and just starts printing when you tell it to. Instead you have to set the temps manually (either with ulticontroller or with Cura printing window).

And note that while M190 and M109 don't move onto the next command until the temperature stabilizes, M140 and M104 move immediately onto the next command and don't wait for the temp to reach the requested value.

Hi, I have tried putting the above code at the end of my start code. Unfortunately it won't work for me. I am using one extruder and heat bed, and my bed takes ages to get hot, so I need for the nozzle to start heating after the bed has reached it's final temp.

With the code above, it does start heating the bed first, but after it reaches the final temp, nothing happens. The extruder does not warm up so it gets stuck there, just mantaining the bed temp.
